MT as Samuel L. Clemens

This is a contract between MT and Isabel V. Lyon, his secretary, dated 13 March 1909 -- it
officially names her his literary and social secretary (she had worked for him over half a decade
already) just a few months before he fired her. His age shows clearly in his handwriting, but
"Samuel L. Clemens" is the signature he uses on almost all the legal documents in the Barrett
Collection, no matter when they were drawn up. He didn't use this signature only on legal
documents, but I haven't seen it often in any other context.
